Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Stack buffer overflow vulnerability in D-Link DIR-513 v1.10 via the curTime parameter to goform/formSetEnableWizard.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Stack buffer overflow in D-Link DIR-513 v1.10 router firmware where the curTime parameter in the goform/formSetEnableWizard web interface function is not properly bounds-checked before being copied to a stack buffer, allowing remote attackers to overwrite stack memory and potentially achieve arbitrary code execution.

MitigationThis is an end-of-life device with no vendor patch available; replace with a currently-supported router model or implement network segmentation to isolate the device if continued operation is unavoidable.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model
    Access the router web admin interface or check the device label to confirm the model is D-Link DIR-513
    Affected if The device is a D-Link DIR-513 router
  2. Check firmware version
    Log into the router web interface and navigate to the Status or System Information page to view the firmware version, or use the command 'cat /proc/version' via telnet/SSH if available
    Affected if Firmware version is 1.10
  3. Verify web interface is enabled
    Attempt to access the router login page at http://[router-ip]/ or check if HTTP service is listening on ports 80/443
    Affected if The web management interface is accessible on the network
  4. Check if goform endpoint responds
    Send an HTTP POST request to http://[router-ip]/goform/formSetEnableWizard with any parameter and observe if the endpoint is reachable
    Affected if The /goform/formSetEnableWizard endpoint is accessible and responds

A user is affected if they have a D-Link DIR-513 router running firmware version 1.10 with the web interface accessible on the network.
